SHUTTLE-BINDER FOR LOOMS.

SPECIFICATION forming part of Letters Patent No. 34 L450, dated June 29,1886.

Application filed November 2, 15 85.

To all whom it may concern.-

Be it known that 1, CHARLES H. KNAPP, of Paterson, county of Passaic,and State of New Jersey, have invented an Improvement in 5ShuttleBinders for Looms, of which the following description, inconnection with the accompanying drawings, is a specification, likeletters on the drawings representing like parts.

This invention, relating to looms, has for its object to improve theconstruction and opera tion of what is known as the shuttle binder,causing it to act also as a check for the shuttle when moved in onedirection, and to release the shuttle quickly after the initial orstarting blow of the picker.

My invention consists in the combination,

' with a shuttle-binder, of a spring-controlled yoke-like check orpresser, substantially as will be described, and pointed out in theclaims.

Figure 1, in plan view, represents a portion of a shuttle-box with myimproved binder and a shuttle. Fig. 2 is a side elevation thereof. Fig.3 shows a blank from which one of the 2 arms of the presser or checklever is made; and Fig. 4 is an edge view of the said blank bent into anoperative position.

The arm A, supposed to be in the plane of the raceway of the lay, andpreferably a projecting portion of the lay, and slitted at A for thepassage of a picker-stick, is of usual construction. The arm Aconstitutes the bottom of the shuttle-box. The back B of the shuttle-boxis attached by the bolts B B B The protector-rod B and the finger B arecommon to many looms-as, for instance, United States Patent No. 8,984,June 1, 1852. The arm A has 9. lug, A slotted at a for the re ception ofthe stud a, made adjustable in the said slot, where it is held by thenut a The stud a forms the fulcrum for the binder, herein shown ascomposed of two pieces, Z) 1), adjustably connected by a bolt, 1) thelatter being extended through a slot, Z), the free end 5 of the part I)being acted upon by the finger B The bolt 13, which connects the back Bwith the piece A which is part of the lay, also serves to hold in placea bracket, 0, having a guide, 0, which is extended through a slot, 0 inthe part b of the binder, preventing the binder from sagging at its freeend.

Serial No. 181,565). (Yo model.)

The binder is acted upon by a steel spring, 0, connected at one end tothe arm A by the screw 0, a second screw, 0, inserted through the saidspring, serving to adjust the inward 5 pressure of the said binder. Thebinder, between its ends, has a stud, d, which forms the fulcrum for apresser or check lover, composed of two concavo-convex arms, d d, aportion of each arm at one end being bent somewhat after the manner of astrap-hinge to form an open loop to hook over the stud d, the loop 20(see Fig. 2) from the arm (1 entering the open slot in the binder andresting upon the loop 21 of the arm (2, the loop 21 also entering thesaid slot. The arm d, at its broad part, has a threaded hole, 40, (seeFig. 3,) into which is screwed in an adjustable manner the screw d", thelatter being extended through a spiral spring and a like hole in the armd before being screwed into the hole 40 of the arm (1, so that the saidspring acts normally to press the free ends, as 3, of the arms dd intothe shuttle-box, the pressure of the shuttle against both of the arms ortheir ends 2 3 tending to compress the spring (1 and consequently putadditional friction upon the shuttle to check its movement. Referring toFig. 3, the narrow projection 20 at one end is that which is bent toform a. loop to embrace the stud d. The arm (2 has a guide-pin, e, fixedto it near one end, which pin is extended through a conical hole in thebinder, after which it receives, as herein shown, a conical nut, e,adjustment of which on the pin 6 determines the extent of inwardmovement of the end 2 of the arm (1; or the said pin may be providedwith any head equivalent to the conical nut. The shuttle S, as it entersthe shuttle-box, first strikes against the inner end, 3, of the arm d,and while passing from the full to the dotted line position, Fig. 1, theshuttle forces the arms c d and the binder outward,

as shown by dotted lines, such movement also turning the independentarms d and d of the g5 check-lever on the stud d, and compressing thespring (1, thus causing the arms d and d to exert greater pressure uponthe side of the shuttle and gradually checking its motion. The shuttle,as it is thrown from the shuttlebox by the usual picker-stick, passesthe end 2 of the arm (1, and thereafter the shuttle is quickly releasedfrom pressure of the checklever by reason of the latter turning upon thestud d.

I am aware that a binder has had pivoted upon it a check-block having aconvexed face; but I am not aware that a presser or check lever which isfree to yield or turn at a point between its ends has ever been employedcomposed of independent arms pivoted with relation to eachother,substantially'-as described, and controlled by a spring, in orderthat the free ends of the presser or check lever may move independently,as herein set forth.

I claim- 1. The binder and the arm to support it combined with theyoke-like presser or check lever comprising two arms, dd, and a springto engage a slot in the said binder, combined with the check-levercomprising two arms, d d, movable toward and from one another and heldtogether and'to the binder by a spring and bolt or stud, substantiallyas described.

3. A supporting arm, A, the binder arranged thereon and provided with astud-receiving hole,combined with the yoke-like yielding presscr orcheck lever composed of the two arms d pivoted to the binder, andthemselves connected by a spring and bolt which tend to draw the saidarms toward each other, and the guide-stud 6, extending from one of saidarms through the stud-receiving hole in the binder and provided with aheaded end to engage the binder, substantially as described.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.
